SPRINGFIELD - With the largest public construction program in Illinois history nearing its end, all of the candidates for governor say the state should approve another one.

But they have different ideas about how to pay for it - from closing corporate tax loopholes to imposing new user fees and partnering with private investors.

Gov. Pat Quinn is a Chicago Democrat who's seeking re-election. He signed the current $31 billion, six-year program into law in 2009. He says the program has created jobs and improved roads and schools across Illinois. He wants the Legislature to consider a new plan this spring.
